While out delivering presents with Santa on Christmas Eve, Rudolph somehow winds up crash-landing in the world of Equestria. He has no idea where he is or how he is going to get back home. Luckily for him, though, the ponies are all so friendly and welcoming, and they offer to do all they can to help him.

It's not often that deer visit Ponyville. A few of its residents have never even met a deer before, much less one who can fly and has a glowing red nose. Some of them seem a little eager to try out this new 'exotic cuisine' they've been given. In only a few short days amongst these curious mares, Rudolph is going to become a very lucky young reindeer.

Rainbow Dash accidentally makes a huge mess out of Derpy's house, leaving the poor mailmare without a place to stay while it gets repaired. Dash begrudgingly agrees to let the clumsy mare stay at her house, though she is definitely not happy about it.

Dash just wants to get through the visit without her entire house coming down, but soon Dash will learn that she shouldn't judge a book by its cover. Perhaps there's just a little more to this wall-eyed mare than meets the eye...
